Abstract

We report measurements of Xi and Xi-bar hyperon absolute yields as a function of rapidity in 158 GeV/c Pb+Pb collisions. At midrapidity, dN/dy = 2.29 +/- 0.12 for Xi, and 0.52 +/- 0.05 for Xi-bar, leading to the ratio of Xi-bar/Xi = 0.23 +/- 0.03. Inverse slope parameters fitted to the measured transverse mass spectra are of the order of 300 MeV near mid-rapidity. The estimated total yield of Xi particles in Pb+Pb central interactions amounts to 7.4 +/- 1.0 per collision. Comparison to Xi production in properly scaled p+p reactions at the same energy reveals a dramatic enhancement (about one order of magnitude) of Xi production in Pb+Pb central collisions over elementary hadron interactions.

Abstract

New data with a minimum bias trigger for 158 GeV/nucleon Pb + Pb have been analyzed. Directed and elliptic flow as a function of rapidity of the particles and centrality of the collision are presented. The centrality dependence of the ratio of elliptic flow to the initial space elliptic anisotropy is compared to models., 4 pages, 4 figures, for the QM99 proceedings

Abstract

First results from the NA49 experiment with a {sup 208}Pb beam on a Pb target at the CERN SPS with total energy of 33 TeV are presented. Data on transverse energy production, forward energy flow and rapidity density of negative hadrons are shown and discussed. The degree of nuclear stopping and the energy densities achieved are estimated for near head-on collisions.

4. Universal centrality and collision energy trends for v2 measurements from 2D angular correlations.

Abstract

We have measured the p t-integrated quadrupole component of two-particle azimuth correlations (related to quantity v2, denoted in this case by v2{2 D}) via two-dimensional (2D) angular autocorrelations on ( η, φ) for unidentified hadrons in Au-Au collisions at 62 and 200 GeV. The 2D autocorrelation provides a method to remove non-quadrupole contributions to v2 (conventionally termed “nonflow”) under the assumption that such processes produce significant dependence on pair-wise relative η within the detector acceptance. We hypothesize, based on empirical observations, that non-quadrupole contributions are dominated by minijets or minimum-bias jets. Using the optical Glauber eccentricity model for initial-state geometry we find simple and accurate universal energy and centrality trends for the quadrupole component. Centrality trends are determined only by the initial state (impact parameter b and center-of-mass energy $\sqrt{s_{\mathit{NN}}}$ ). There is no apparent dependence on evolving system dynamics (e.g., equation of state or number of secondary collisions). Our measurements of the quadrupole and non-quadrupole components have implications for the contributions to v2. They suggest that the main source of the difference between v2{2} and v2{4} (or v2{2 D}) is measured properties of minijets. [ABSTRACT FROM AUTHOR]
